A beautiful crystalline compound, silicon carbide (SiC), consisting of carbon and silicon in combination; -- also called carbon silicide. It is made by heating carbon and sand together in an electric furnace. The commercial article is dark-colored and iridescent. It is harder than emery, and is used as an abrasive.
Commercial form of silicon carbide, an abrasive powder used to create tonal areas on plates or to grain litho stones.
An abrasive powdered mixture, primarily silicon carbide, used to produce a dotted or tonal effect when the plate is passed through a press. Similar to a sandpaper ground.
Used extensively as a grinding compound and in abrasive wheels. Chemical name: Silicon carbide Chemical formula: SiC See also: Chemical Table.
an abrasive composed of silicon carbide crystals
Silicon carbide used for abrasive. Silicon carbide wheels (called "green grit" because they are green in colour) are used for sharpening cemented carbide tipped tools but they are not recommended for HSS tools. The Carborundum company also make aluminium oxide wheels - which has been known to cause some confusion! The grey wheels on cheap grinders are corundum (impure aluminium oxide) not carborundum.
An intaglio process whereby a very hard, fine abrasive powder, silicon carbide, is used to impart a fine grain or surface tooth to a printing plate.
The trade name for silicon carbide, carborundum began its use in printmaking as an abrasive which was used in affacing lithographic stones. The Particles, when mixed together with glue can also be used to draw on a plate - sometimes creating a raised surface - which is then inked and printed with the ink being held in the spaces between the particles. The resulting prints are often textured due to the raised areas of the printing surface.
An abrasive in either solid or powder form, used for sharpening engraving and lino cutting tools or for grinding the old surface off lithography stones.
Trade name of an abrasive composed of alumina, silicon carbide, etc.
